roms: Add OpenSBI version 0.4 Add OpenSBI version 0.4 as a git submodule and as a prebult binary. OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source reference implementation of the RISC-V Supervisor Binary Interface (SBI) specifications for platform-specific firmwares executing in M-mode. For all supported platforms, OpenSBI provides several runtime firmware examples. These example firmwares can be used to replace the legacy riscv-pk bootloader and enable the use of well-known bootloaders such as U-Boot. OpenSBI is distributed under the terms of the BSD 2-clause license ("Simplified BSD License" or "FreeBSD License", SPDX: BSD-2-Clause). OpenSBI source code also contains code reused from other projects desribed here: https://github.com/riscv/opensbi/blob/master/ThirdPartyNotices.md. In this case all of the code we are using from OpenSBI is BSD 2-clause as we aren't using the Kendryte code (Apache-2.0) with QEMU and libfdt is dual licensed as BSD 2-clause (and GPL-2.0+). OpenSBI isn't being linked with QEMU either it is just being included with QEMU.

The QEMU distribution includes both the QEMU emulator and
various firmware files. These are separate programs that are
distributed together for our users' convenience, and they have
separate licenses.

1) The QEMU emulator as a whole is released under the GNU General
Public License, version 2.
2) Parts of the QEMU emulator have specific licenses which are compatible
with the GNU General Public License, version 2. Hence each source file
contains its own licensing information. Source files with no licensing
information are released under the GNU General Public License, version
2 or (at your option) any later version.

LICENSE: clarify 1) The GPL says that "if the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation". This is not true, QEMU includes parts that are v2-only. 2) Provide a default for files with no licensing information. 3) It is not just hardware emulation that is under BSD license. 4) Restrict GPLv2-only contributions to user mode emulation (due to code from Linux) and PCI passthrough (due to code from Neocleus). 5) The rules were initially set by Fabrice but are being amended by other people (already in commit ee12e1f, LICENSE: There is no libqemu.a anymore, 2011-11-15). Do not put words in his mouth.

tcg/LICENSE: Remove out of date claim about TCG subdirectory licensing Since 2008 the tcg/LICENSE file has not changed: it claims that everything under tcg/ is BSD-licensed. This is not true and hasn't been true for years: in 2013 we accepted the tcg/aarch64 target code under a GPLv2-or-later license statement. We also have generic vector optimisation code under the LGPL2.1-or-later, and the TCI backend is GPLv2-or-later. Further, many of the files are not BSD licensed but MIT licensed. We don't really consider the tcg subdirectory to be a distinct part of QEMU anyway. Remove the LICENSE file, since claiming false information about the license of the code is confusing. Update the main project LICENSE file also to be clearer about the licenses used by TCG.

3) The Tiny Code Generator (TCG) is mostly under the BSD or MIT licenses;
but some parts may be GPLv2 or other licenses. Again, see the
specific licensing information in each source file.
